Explanation of responses

• F1The Ordinary Shares may be represented by American Depositary Shares, each of which currently represents one Ordinary Share.
• F2On June 24, 2026, Eli Lilly and Company ("Parent"), through its wholly owned subsidiary LDH XV Corporation ("Purchaser"), acquired all outstanding Ordinary Shares of Centessa Pharmaceuticals plc (the "Company") by means of a scheme of arrangement under Part 26 of the UK Companies Act 2006 (the "Scheme of Arrangement"), pursuant to the Transaction Agreement dated as of March 31, 2026, by and among the Company, Parent and Purchaser (the "Transaction Agreement").
• F3At the effective time of the Scheme of Arrangement (the "Effective Time"), holders of Ordinary Shares became entitled to receive (a) $38.00 in cash per Ordinary Share (the "Cash Consideration"), without interest and less any applicable withholding taxes, and (b) one non-transferable contingent value right (a "CVR") entitling the holders to receive contingent payments of up to an aggregate of $9.00 per Ordinary Share, without interest and less any applicable withholding taxes, contingent upon the achievement of specified milestones set forth in the Contingent Value Rights Agreement between Parent, Purchaser and a rights agent mutually agreeable to the Company and Parent. Because each ADS represents one Ordinary Share, holders of ADSs became entitled to the same per-share consideration of $38.00 in cash plus one CVR per ADS.
• F4(continued from footnote 3) The transfer of Ordinary Shares occurred automatically at the Effective Time pursuant to the Scheme of Arrangement, without any action by or discretion of the Reporting Person.
• F5Includes 98,025 Ordinary Shares underlying Restricted Share Units ("RSUs"). Each RSU represented a contingent right to receive one Ordinary Share of the Company. Pursuant to the Transaction Agreement, at the Effective Time, each outstanding and unvested RSU became fully vested, and at the Effective Time, each RSU was automatically cancelled and converted into the right to receive (i) $38.00 in cash per Ordinary Share underlying such RSU award, without interest and less applicable withholding taxes, and (ii) one CVR per underlying Ordinary Share, in each case in accordance with the Transaction Agreement. No Ordinary Shares were issued upon settlement of RSUs prior to the Effective Time.
• F6Pursuant to the Transaction Agreement at the Effective Time, each outstanding share option, whether or not vested, was automatically cancelled and converted into the right to receive (i) an amount in cash equal to the excess of the Cash Consideration over the per-share exercise price of such option, without interest and less applicable withholding taxes, and (ii) one CVR per underlying Ordinary Share, in each case in accordance with the Transaction Agreement. No share options were exercised prior to the Effective Time.
